Irssi authenticates via SASL, still attempts to log in as username

Question

So I'm using Irssi 0.8.17 with Fedora 22 (installed through dnf) and configured SASL authentication and SSL for Freenode. I can authenticate using the credentials I've supplied in an ~/.irssi/sasl.auth file (automatically generated via /sasl set Freenode primary-nick password PLAIN). However, I am for some reason automatically logging in as my local username in addition to my irc nick and I can't figure out how to stop the unwanted behavior.

I took the cap_sasl.pl script from Freenode's website https://freenode.net/sasl/sasl-irssi.shtml .

Added the Gandi ssl cert and converted it from a crt to a pem file.

created ~/.irssi/sasl.auth

I stripped my ~/.irssi/config to the bare minimum

servers = (   {
    address = "chat.freenode.net";
    chatnet = "Freenode";
    port = "6697";
    use_ssl = "yes";
    ssl_verify = "yes";
    ssl_cacert = "~/.irssi/certs/*.pem";
    autoconnect = "yes";   }, );

settings = {   
    "fe-text" = { actlist_sort = "refnum"; };
};

chatnets = {
    Freenode = { type = "IRC"; };
};

However, I still log in to Freenode twice and I don't understand why. I have not touched the stuff /usr/share/irssi.

Fixed the issue, change chatnets to

chatnets = {
    Freenode = { type = "IRC"; nick="IRC-NICK" };
};

Update: also, I removed write permissions chmod -w ~/.irssi/config to prevent irssi from creating a new core settings line with real-name et al in it. YMMV.
